Choose your case type to see the supporting documents applicants are most often asked for — and which ones need a certified English translation if they’re not in English.
Most checklist documents are 1–2 light pages — typically $10–$20 each at Corpus’s 8¢/word rate (capped at $19.99/page — you pay whichever is lower), certification included. Start your order or get a free quote.
This checklist is general information, not legal advice. Document requirements vary by case — always follow your form instructions, USCIS/NVC notices, or your attorney’s guidance.
Only documents that are not in English. Each foreign-language document must be submitted with a complete English translation and a signed translator certification (8 CFR 103.2(b)(3)).
USCIS expects the translator to certify they are competent to translate and that the translation is accurate. Self-translations are widely discouraged and frequently questioned; a professional certified translation avoids RFE risk for a small cost.
Corpus Localization delivers most certified translations within 24 hours as a certification-ready PDF, at 8¢ per word or $19.99 per page — whichever is lower.
